6 bolt build

[3slow]

I recently purchased a 6 bolt motor that I will dropping into my 91 TSI and I am looking for a little guidance. I am thinking about the 2.3 stroker kit from Eagle, but when I searched it seemed to be more bad than good about it.

1000cc injectors, dsm link, meth injection

My goal is 25 psi of boost. What turbo would you recommend with moderate spool time for lots of drag racing and the occasional autoX.

Will the shep trans stage 1 or 2 rebuild hold up?

Thanks

If I was you man, probably a stage 3 with a welded diff instead of the 4 spider if your looking at drag racing. Thats my opinion, whatever your budget desires is what you should get.

Did you not read this?

and the occasional autoX.

Now i know pretty much nothing about autoX, but i would presume you would want to be able to turn. As for a turbo i vote garret3076 aka fp3052. Of course I'm biased, but it seems that it would fit your goals. Good luck.

My buddy has a 2.3 stroker kit. Wiseco pistons and Eagle rods. His wastegate is ####ed up so he's only at 3 pounds.

You can't even hear the BOV anymore. Its all motor practically and it is sick. I can't wait till I stroke mine.

The only bad thing is that you can't rev as high, but with some head and tranny work. That can be changed!

Defenitely do a stroker. More low end torque, turbo spools like there is no tomorrow.

A 50 trim spools/ behaves like a EVo III 16g with a stroker!

It sounds like you are more of a drag racer than an auto-X. If you have a 2.3L stroker with 1000cc injectors, dsmlink, 25PSI and meth injection you probably want a 57trim or 60-1 turbo. This setup would be bad for auto-X because the large turbo will lag. Honestly I would recommend building a purpose oriented car either drag OR auto-X.

So a badass build entails: 2.3 stroker, 1000CC injectors, shep trans rebuild, garrett gt30 turbo, meth injection, dsm link.

Do you guys think 1000CC injectors will cover it?

What do you think of the forced performance Green model turbo?

Thanks guys

Ya, you might be right on that. I will just do autocross for fun in my mazda or try to with the big turbo on the dsm.

 

[gsxtasy]

1000cc injectors will handle quite a bit, depending on the type of fuel your running. Pump gas and race fuel, they should be fine, if you venture into e85 land, they will be more limited.

edit: The green is a great turbo that has proven it self over and over. It may be on the smaller side of things you would want to run on a stroker, but it would be fun, nonetheless. However, if your looking at all out drag now, i'd look into the newer HTA 35r's they seem to be amazing from the reviews so far, but they're kinda pricey.

Just to let you know, ludachris (View Profile: Ludachris - DSMtuners.com) does autox with a 2.3l stroker. He's running and FP3150.

Any opinions on the stroker kits themselves. SlowBoyRacing has an eagle stroker kit for $1800 and another kit for $1600-1700. I am farely new to the dsm scene so what do you guys like as far as rods and pistons go?

 

[buddahboost]

I recommend Wiseco pistons and Eagle rods. Its really up to you. There's mahley too.

If you are doing link, I would at least recommend going bigger than 1000cc. You can dial them in with link so its not an issue.

I'm going to be running link and 1600cc eventually with E85 daily pushing hopefully 25 pounds of boost on a stroker.

The bigger injectors will give you room to grow and you don't have to buy twice.

I disagree, if you aren't going to run e85 or expecting a really big number on the dyno, i don't think 1600cc injectors are needed, yes you *could* use them, but you will probably not appreciate the idling and cruise with them. This being because they are pintle style injectors instead of ball and seat injectors. They are more easily dealt with on e85 due to the need for more fuel. The biggest i would go for now is 1150's, which will take you a long ways, and still have stock characteristics as far as idling and dialing them in.

Are you planning on running 600+whp? Cause 1000's and link will handle that all day. I would also suggest the FP3052 for it's quick spool up and capability of making big numbers.
Now if I was use I'd save the cash and build a 2.0. Let that thing rev like it wants to.

What do you think I should get as far as cams go? 272 or 280s? The 280's need double spring's, no?

At 25 PSI of boost, which maf should I go with? What compression on the pistons also?

I don't know why you are bound and determined to run 25psi, why not get a turbo first and run it where it wants to be run? Without knowing what turbo, we'll have no idea what kinda air you'll be running through your mas. For a simple answer, a 2g mas will suite you fine. Piston compression also depends on what your doing. For a simple answer there, 8.5:1. Do some research and you will find the answers to all your questions.

 

[3slow]

My tuner said that on pump gas with meth injection, 25 PSI is probably the highest boost I can run without knock. The FP3052 sounds like the turbo I will go with. Wiseco has 8.3:1 pistons.

 

[gsxtasy]

Did your "tuner" know what turbo you were planning on running? The amount of lbs of boost you run is relative, but i digress. Here, a 2 second search found this.

I have a 2.3 running eagle rods, ross 9:1 pistons (all cryo'd and pistons ceramic topped and teflon coated). I originally used a G4CS crank that I had butchered and cryo'd but it developed a hairline crack. I now have a eagle 100mm crank I figured if it is good enough for the AMS stroker kit it's good enough for me. With enough fuel and timing control you can eliminate all knock. I have a precision 6152RE (630 hp) waiting to go on. The 5027E (440 hp) I had wound up like crazy 27-30 psi by 3300 easy. I don't understand the 25 psi limit? A fully built motor tuned correctly can handle 50+. If you don't beleive me check out SCC 7/07 all the evo's ar running 40psi and a few are running 50+ (GT42R baby) so your psi limit seems a little ridiculous. Plus it all depends on the turbo like gsxtasy stated.

 

[3slow]

I'm staying on pump gas and meth injection though. Yes 30+ may be possible with C16, but I will be driving this car on the street too and I don't want to pay that much for race fuel. The gt3076 seems like a good compromise for street/strip results.

 

[lasertrash]

I only ran 101 91 plus meth should take you higher than that i beleive? If not just throw in some toulene it's cheap and effective.

 

[3slow]

So I should ditch the 1g maf and get the 2g? Will I be outflowing it?

 

[lasertrash]

I haven't seen the max on a 2g maf yet, I've read it's like 550 but have personally seen much more than that run at the wheels on one. Super easy to install on 1g. 1g maf=trash. I'm looking into doing an evo 8 maf I'm not real sure of the gains but I have seen a couple of guys running them. On the 2g maf (and 1g for that matter) you can remove the lower honeycomb and increase flow as long as you adjust the fuel for the unread air.

Crower 272/272 cams on extreme psi for $450 right now. I have been looking for parts on DsmParts, SlowBoyRacing, and Extreme PSI. Any other good places to look (besides Ebay)?

 

[lasertrash]

For that price I would run a set of FP3x's. Thaey are proven and designed for the stroker motor. The only thing is you have to run double wounds with them but you can get a set of supertech's from them for relatively inexpensive. I'm running them and think they are great smooth idle and great power.
